For satisfactory results it is, of course, necessarythat the completed glowers of a given rating should be uniform asto resistance, and by means of a beautiful arrangement due to W. Hanks, this is as exactly as possible to Figs. 3, 4 and 5, it will be seen that a number of glow-ers are mounted on a revolving stand and the lower ends in turnbrought under the influence of an arc between two carbons. A mag-nified image of the glower and the arc is thrown on a screen in frontof the operator, and also the image of a gauge line. .\s witnessed in.

The glowers, while perhaps intrinsicallymore fragile than the carbon filament, are, owing to their muchgreater cross section, quite sturdy when mounted and not subjectto breakage in ordinary handling. Perhaps the most troublesome problem presented in the develop-ment of the \ernst lamp was in connection with the glower ter-minals. The final solution as found by Mr. Marshall W. Hanks,consisted of embedding a platinum bead in the end of the glower actual operation, as soon as the glower treminal comes within theinfluence of the arc, it is seen to swell and gradually but rapidlyan almost perfectly spherical globule forms on the end; as this latterincreases in size it approaches the gauge line, and when it becomestangent with it, the operator revolves t
